Filed: 1972-03-16
Abstract: 1370221 Impulse transmitters STANDARD TELEPHONES & CABLES Ltd 16 March 1972 12354/72 Heading H4K [Also in Division G4]  In a selective signalling apparatus, e.g. a push button operated telephone, a set of contacts forming at least some of the contacts operated by pushbuttons to provide a coded condition are connected such that when operated a strobe signal is activated to connect the coded condition to a signal generator. In the instrument shown sixteen buttons are provided with common column contacts X1-X4 and common row contacts Y1-Y4 so that operation of each pushbutton is uniquely signalled to a coding circuit by closure of a respective pair of contacts. A strobe signal is provided for transmitting on the output of the coding circuit and this strobe signal is generated when any one of contacts X1-X4 are operated. Since one of these contacts will always need to be operated a separate common strobe signal contact can be dispensed with. Preferably the contacts X1- X4 close after the contacts Y1-Y4. In a modification each pushbutton controls its own pair of contacts one of which is connected additionally to the strobe signal supply, Fig. 3 (not shown). Diodes are used to ensure that spurious operation does not occur.

Abstract: 990,711. Tumbler driers. McGRAW-EDISON CO. March 29, 1963 [March 30, 1962], No. 12536/63. Heading F4G. A tumbler drier comprises a controllable heater for passing hot air at one of two predetermined temperatures through the drier drum, means for modulating the heater at each of the temperature levels, and further means to control the heater when the residual moisture of the material to be dried reaches a predetermined minimum. The hot air supplied to a tumbler drier drum 12, Fig. 1, by a gas burner 20 from a distributer 14 in a duct 16 and drawn therethrough by a fan 22 to an exhaust opening 24, is so controlled by means which effect drying at as high a temperature as possible during the initial drying stage while modulating the heat supplied in proportion to the increase in dryness of the materials until a predetermined low level moisture content is achieved, and thereafter reducing heat input to a low level sufficient to dry but not damage the material. The control means comprise a modulating valve 32 in a gas supply line 28, which valve contains a port 34, Fig. 2, a valve disc 36 supported by an expandible stem 38 and a bellows 40 operated by a fluid from a sensing bulb 44 in the path of the exhaust air to progressively close the valve 36 to a fixed position wherein the gas supply to the burner is reduced as the temperature of the exhaust air increases on drying of the materials. Thereafter the valve 36 is controlled by a sensing bulb 52 adjacent the distributer 14 in the path of the air supply which controls a heating coil 46 about the stem 38 to move the disc to a second, low capacity position relative to the port 34 to establish a low level of heat input sufficient not to damage the load but consistent with a maximum exhaust temperature.
